In Neal Stephenson's 2008 novel Anathem, Fraa Jad has technology that allows him to take advantage of quantum immortality.

In Dan Simmons' Ilium/Olympos duology a mechanism similar to quantum immortality protects the character of Achilles.

In Donald Schneider's short story "Pride's Prison," [1] the ending of the piece strongly suggests quantum immortality

In Alastair Reynolds' short story Everlasting (from the collection Zima Blue) Ian Caldicot explicitly states the many-worlds justification and proceeds to commit apparent suicide, but the story ends ambiguously with the survival of the protagonist Moira Curbishley in unlikely circumstances following an accident.

The episode Perfect Circles in the third season of Six Feet Under contains references and allusions to quantum immortality, as a major character observes several possible outcomes of his life.

In Fringe, Peter Bishop finds himself transported to an altered timeline which includes the living versions of characters otherwise dead in the original timeline if it weren't for his actions involving a bio-mechanical doomsday device reversing past events in which time is reset.

In David Lindsay-Abaire's play Rabbit Hole, a grieving mother takes solace in the possibility that her dead son may enjoy quantum immortality. She comes to prefer to believe that this world in which she lives may simply be a "sadder version" of other co-existing, parallel universes. Rabbit Hole won the 2007 Pulitzer Prize for Drama.

In The Prestige, Robert Angier (Hugh Jackman) repeatedly duplicates himself and kills his previous copy; his continued belief in the survival of his consciousness in the new (living) copy mirrors the principles of quantum immortality without utilizing parallel universes.

In Source Code, Capt. Colter Stevens (Jake Gyllenhaal) repeatedly experiences "death" as he investigates the bombing of a train. Ultimately, he survives in the universe where the train was not bombed and no one died.

In the Stargate series, as well as plenty of other science fiction TV shows, the writers regularly brought back "dead" characters for an episode using this mechanic. They also used it to temporarily "kill" characters; in episodes where the timeline is altered and must be fixed, regulars were sometimes killed before the rest of the team finally fixed the timeline, restoring the killed characters in the process.

Another character, who is discovered to be dead prior to the game's events, periodically makes an appearance throughout the game, suggesting that she has achieved immortality.

There is a modified SNESemulator called the Many-Worlds Emulator that creates a new video recording each time the user loads from a previous save state (or, equivalently, a branch point). These videos are then flattened into one, depicting many possible outcomes from a set of choices the user makes. [2]

In a later part of the same story arc, a character travels between alternate timelines defined by other characters being alive or dead. In each timeline, circumstances have changed (sometimes dramatically) to rationally explain why they are alive or dead.
